TDK-Lambda has introduced two new series of EPCOS MMKP capacitors which employ a film that is metallised on both sides.
They offer particularly high pulse strength as well as high current capability: depending on the type and frequency, the permissible current can be in excess of 10 ARMS.
The B32641B* and B 32642B* families have dimensions of between 4 x 9 x 13 mm and 11 x 18,5 x 18 mm, and are available with lead spacings of 10 mm and 15 mm. They are designed for voltages of 630 V or 1000 V d.c. and cover a capacitance range from 4,7 nF to 150 nF, in operating temperatures up to +110°C.
The principal applications are circuits that operate with high frequencies and currents, including resonant circuits of power supplies with an LLC topology. The MMKP capacitors are also suitable for use in switch-mode power supplies or ballasts for lighting systems.
